ABC will likely rejigger its Sunday-night lineup next season – moving “Grey’s Anatomy” or “Desperate Housewives” to a different night.

The move would free up some valuable real estate for one of three incoming shows ABC holds in high regard.

It would also give ABC a jolt elsewhere on its schedule, since both “Housewives” and “Grey’s” average over 20 million viewers a week as two of TV’s hottest shows.

A Sunday re-shuffling is likely, considering the network is high on three pilots – “Men in Trees” (starring Anne Heche), “Brothers & Sisters” and “Women in Law” – that it envisions airing on Sunday, ABC entertainment exec Jeff Bader told The Hollywood Reporter.

“We have three big shows on Sunday, so there will be pressure to spread the wealth,” Bader said.

(The third “big” show is “Extreme Makeover: Home Edition,” which is a dark-horse candidate to move nights.)

The most probable night for a “Grey’s” or “Housewives” infusion would be Monday, since ABC no longer has “Monday Night Football” to prop up its prime-time schedule through the fall.
